Brain zap test may spot dementia early in Parkinson's
NCT ID NCT06835595
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses a non-invasive brain stimulation technique called TMS to measure brain activity in 52 people with Parkinson's disease. The goal is to see if these measurements can tell the difference between normal thinking, mild cognitive impairment, and dementia, and predict future decline. No treatment is given—only observation and testing.

Inclusion Criteria: * Age \> 18 years * Ability to undergo an extensive neuropsychological evaluation * Ability to sign informed consent for the study * Diagnosed with idiopathic PD according to the latest revision of the MDS criteria * On stable and optimal antiparkinsonian therapy for at least four weeks Exclusion Criteria: * Systemic diseases of significant severity, including cardiovascular and cerebrovascular conditions (e.g., active neoplasms requiring chemotherapy, or end-stage heart failure) * Presence of any active neurological disease, in addition to PD * Presence of a cochlear implant, ferromagnetic brain device or near the site of brain stimulation, pacemaker, brain electrodes for DBS, electromechanical devices with IPG, or any other implantable stimulator, including peripheral ones * History of epilepsy * History of cerebrovascular, tumor-related, infectious, or metabolic brain conditions predisposing to seizures or causing symptomatic epilepsy * Pregnancy or breastfeeding * Alcoholism * Treatment with anticholinesterase drugs, benzodiazepines, neuroleptics, anticholinergics, or antidepressants in the last month * Treatment with drugs that lower the seizure threshold (e.g., imipramine, amitriptyline, doxepin, nortriptyline, maprotiline, chlorpromazine, clozapine, foscarnet, ganciclovir, ritonavir, amphetamines, cocaine, MDMA, ecstasy, phencyclidine, ketamine, gamma-hydroxybutyrate, alcohol, theophylline) * Active cochlear pathology (especially if currently receiving ototoxic drugs, such as aminoglycoside antibiotics) * Dementia according to the latest revision of the MDS criteria for PDD
